Bump version in released font files

[mkeller]

The version number in the font files from Google Fonts, Github release v2.0.3, and in the Github master branch all say Version 2.001, although the latest version seems to be 2.0.3.

Before the next release, please bump the version number. If you update the files in the master branch without producing an actual release, you should put something like 2.0.4-alpha there.

Not applying proper versioning makes it hard to track things like #45.
